CYLINDER-LO CK.

lock construction which may be used advantageously as a lock for doors, either.

swinglng or sliding doors, and also as a lock for securing a spare tire on the tirerack of an automobile. It is to be understood, however, that the lock may be used in a great many other relations.

A preferred embodiment of the invention is illustrated in the accompanying drawings in which Figure 1 is a view showing the lock applied to a swinging door; Fig. 2 is a fragmentary view showing the lock employed to hold the tire on the tire-rack; Fig. 3 is a longitudinal sectional View of the lock; Fig. 4 is a like sectional vie-w of the-body of the lock illustrating the interior arrangement thereof; Fig. 5 is a sectional view on the line 5-5, Fig. 3, showing the locking mechanism in osition to permit the separation of the b0 y and locking cylinder; Fig. 6 is also a sectional view on the line 6-6, Fig. 3, but showing the parts turned in locking position; Fig. 7 is a sectional view on the line 7-7, Fig. "3; and Fig. 8 is a sectional view on the line 8-8, Fig. 3. i

In the embodiment of my invention herein selected for illustration, and referring first to Fig. 3, 1 is the body member of the lock, which is provided with a head 2 and with a hollow cylindrical portion 3. This hollow cylindrical portion is grooved interiorly on opposite sides, as shown at 4 and 5, and the rear of the grooved portion of the cylindrical part of the body is cut away as at 6 and also at 7. It will be seen that these cutaway portions 6 and 7 are at the extreme rear of the cylindrical portion 3 of the body.

The portion of the lock complemental to the body portion 1 consists of a removable cylindrical member 8 provided with a head 9 adapted to fit against the end of the body portion 1 when the cylindrical member is slid into the cylinder portion of the body of the look. For convenience, I will term this Specification of Letters Patent.

removable member 8 as the lock-cylinder. This lock-cylinder is provided at opposite sides with ribs 10 and 11. These ribs are adapted to slide into the grooves 4 and 5 of the lock-body 1 when the parts of the lock are assembled. Within the lockcylinder 8 is mounted what I will term the key-bolt 12. This key-bolt is provided with a key-hole 13, and extending across the rear end of the key-bolt is the lock-'bolt-14. This lock-bolt 14 may be given a driving fit in the key-bolt 12, or may be otherwise secured thereto in any desired manner. It will be noted, however, that in order to mount the key-bolt 12 with its lock-bolt 14 within the lock-cylinder 8, it is necessary to fit the key-bolt 12 into the lock-cylinder, bringing the passage of the key-bolt which receives the lock-bolt 14 into register with corresponding openings 15-15 in the lock-cylinder 8. As illustrated in Fig. 5, these openings or slots 15-15 extend partially around the circumference of the lock-cylinder 8 to permit the lock-bolt 14 to be turned into locking position behind the shoulders 16-16 formed by arcuate slots 6-7, Figs. 4 and 8, formed at the rear end of the cylindrical portion 3 of the lock-body 1.

In order that the key-bolt 12 may be locked against turning when the key is withdrawn, this key-bolt and the lock-cylinder 8 are provided with suitable tumbler mechanism 18, as indicated in Fig. 3 and in Fig. 7, so that when the key properly positions the tumblers to break along the exterior surface of the key-bolt, as at 19 for example, Figs. 3 and 7, the key-bolt together with the locking-bolt 14 may be turned either to the proper positions for disengaging the lock cylinder with its head 9 from the body of the lock, or to engage the same therewith.

For example, the parts of the lock are assembled by sliding the lock-cylinder 8 into the cylindrical portion of the lock-body 1 and with the ribs 10 and 11 engaging the grooves 4 and 5, respectively, of the lockbody. During this assembly, the transverse lock-bolt is, of course, held in alinement with the ribs 10 and 11 so that this lock-bolt also may slide into the lock-body through the grooves 4 and 5. WVhen the lock-cylinder with its lock-bolt is seated within the looking body, the key-bolt 12 together with the locking-bolt 14 may be iven a partial turn, bringing the ends of tie lock-bolt behind the shoulders 16 at the rear of the cylindrical portion of the lock-body.

Conversely, in order to separate the parts of the lock, the key is inserted in the keyhole 13; the key-bolt is turned to bring the transverse locking-bolt into alinement with the grooves 4 and 5 whereupon the lock-cylinder with its head 9 may be drawn out of the locking body 1.

This form of lock is obviously adapted to a great variety of uses. One of the principal uses which I contemplate at the present time is shown in Fig. 1 in which the lock is applied to a door 20 hinged at 21 to the frame 22. The door-jamb is provided with any suitable form of hasp 23, which may be bolted to the door-jamb at 24 and may have a hinged part 25, which is adapted to slip over the outer end of the lock-cylinder 1, which is embedded in and whose head rests against the inner side of the door 20. When the locking member 8 is slipped into place, its head 9 rests on the hasp. and holds it in locking position.

In Fig. 2, I illustrate the securing of a spare automobile tire and rim on the extra tlre support of an automobile. In this application, the lock is shown as engaged with theopposite ends of, a tire-holding bail 27, thus supporting the tire 28 with its rim 29 on the spare tire support 30 of an automobile or the like.

While I have herein described a particular embodiment of my invention and a particular arrangement and construction of the parts, and have indicated a special application or use of the invention, it is to be understood that the invention may be varied in these details within the scope of the appended claims.

What I claim is:

1. In a lock, the combination of a lockbody including a locking head extending transverse to the lock-body, a portion extending from said head having a recess formed therein, and a locking member comprising a head and having locking means adapted to be locked in said recess, said head abutting against the extending portion of said lock body, whereby there is an unbroken surface between said heads.

2. In a lock, the combination of a lockbody having a head, a recess within said body, a locking member having a part adapted to fit within said recess, said part having a head, a key-bolt carried by said locking member and adapted to rotate therein, said key-bolt having a lock-bolt adapted to be turned by a key into and out of locking engagement with said lock-body. 3. A lock comprising a body member having a head at one end and having a recess in its opposite end, a complemental locking member comprising a part adapted to slide within said recess and having a head comlemental to the head on the body portion, ray-operated locking means within said complemental locking member, said means comprising a member to be turned by means of a key into and out of engagement with the lock-body.

4. A lock comprising a lock-body having a head at one end and having a recess within its opposite end, a complemental look ing member having a head complemental to the head of the lock-body and having a part adapted to be slid within the recess of the lock-body, means to prevent the rotation. of said part within the lock-body said complemental part carrying a key-bolt having a cross-head adapted to .be located within the recess of the lock-body when the parts are: assembled, locking mechanism whereby said key-bolt may be freed by a proper key for rotation within the complemental locking member, whereby said crossbolt may be engaged with and disengaged {groin locking shoulders carried by said lock- 5. A look comprising a lock-body having a head at one end and having a recess within its opposite end, a complemental locking member having a head and having a part adapted to be received within the recess of the locking body, said locking body having ofi'set recesses near the inner end of its recess, said complemental part carrying a rotatable member adapted to be released for rotation within the complemental part by means of a key, said rotatable member having a cross-head near its inner end adapted to extend into the offset recesses of said lock-body, the parts being so constructed and arranged that said cross-head may be turned into and out of engagement with looking shoulders within the recess of the lock-body by means of the key.

In testimony whereof I, the said CHARLES P. READ, have hereunto set my hand.
